Wrapped the spar box, which completes this step of the wing build process
3 times around with 180mm by 2100mm 500gr UD finished with peel ply. My box cir-cum reference was about 68cm, so x3 and rounded to 210cm to ensure a bit of overlap. This was done after 4 layers 400gr bi-ax was put around the middle area of the spar plank top to bottom to fill the flat area where the top and bottom bi-ax cap did not reach. My sections I made 90mm x 200mm and then I sanded down the overlap areas to give it a completely flat spar plank face for the UD wrap to follow.

Not much building going on, but moved the wings back to the dolly to free up space so I can start working on the rudder, H-stab, ailerons and flaps. This is mostly sheeting work, but I look forward to getting it done so I can start the assembly, after which my Whisper will really start to look like an aircraft

Finally back to work on the rudder. After replacing the VStab fin skins with the carbon ones, I fit the rudder again to make sure of the fitment and the width at the counter balance horn. Thankfully this seems to be good. I did take of very thin layer of foam from the side still to be covered to compensate for the .5mm thickness of the carbon when I sheet it.
Before I can get to sheeting, I trimmed the trailing edge using a straight edge and then sanded it with a 50cm long block to make sure it is straight. This was required as I want to install the trim tab into the trailing edge before I put the final sheet on. So, before I could do this, I sanded the trailing edge and then put a bit of flox on the trailing edge just where the polystyrene was trimmed away to smooth the sharp uneven edge. I did this because I put down another layer of carbon UD, just the width of the trailing edge, but I put the inside edge up onto the polystyrene, over the flox bed I prepared. After ensure a good wet out, I stalled the trim tab using flox, smoothing the edges with flox. I then finished everything with peelply and laid a straight edge over the the peelply and weighted it down with dive weights.
The rudder was put on the polystyrene cradle from which it was cut to ensure a straig trailing edge. I trust I'll get the perfect edge I'm after with a solid trim tab.
The plan is to put another 2 layers of UD over the the trailing edge and trimtab before the final carbon sheeting is done.

Trial fitment of rudder with the new carbon skins. Also trimmed the skins trailing edge so they are equal
